He was so sweet, so innocent. All he loved doing was cooking tacos, listen to his brothers puns, and try to be friends with everyone.
Then you're pushed down a hole and end up in this strange new underground. After seeing you, his sanity breaks. Instead of making tacos, he loves hearing bones pop. Instead of listening to his brothers jokes, he bathes in blood. Instead of making friends with everyone, he kills them.
